Batteries And Generators Are Different Things

It drives me crazy when sales people suggest that installing their lithium batteries automatically means we don’t need a generator.

Batteries are a storage device, generators are…wait for it…a generation device. They are different things.

Sure, installing a larger capacity battery bank (of any chemistry) might mean that we can anchor for longer, or sail for longer, without starting a charging source, but eventually, and in some way, those batteries will need charging…duh.

And if we have enough solar to never need a generator, then we might not even need lithium batteries.

Point being that confusing this basic difference between batteries and generators, sets us up to make bad system design decisions…and often spend our money unnecessarily.

Navico should know better.

More on the generator decision here (needs updating).
